Lab Assignments• There will be weekly lab assignments. • The labs will count 30% of your final

grade.• The assignments are usually 1 week

assignments, sometimes 2 weeks for the less small ones.

• The assignments will be closely connected to the class content. Working on them will show you if you really understood the topic.

CIS 068

Policy on CheatingProgramming must be learned by

doing it !• Copying another student’s program

deprives you of that learning opportunity.

• If a lab assignment is found to be a copy, both students will receive a –10 for that assignment.

• If more than one program is found to be a copy, the students involved will receive an F for the course.
